Aleksei A. Navalny, an anticorruption activist who for more than a decade led the political opposition in President Vladimir V. Putin’s Russia while enduring arrests, assaults and a near-fatal poisoning, died Friday in a Russian prison, according to Russia’s Federal Penitentiary Service.
The prison authorities said that Mr. Navalny lost consciousness on Friday after taking a walk in the Arctic penal colony where he was moved late last year.
He was last seen on Thursday, when he had appeared in a court hearing via video link, smiling behind the bars of a cell and making jokes.
Kira Yarmysh, Navalny’s press secretary, said in a live broadcast Friday that Navalny’s advisers were not yet able to issue an official confirmation of his death but believed that he had perished.
Despite increasingly harsh conditions, including repeated stints in solitary confinement, he maintained a presence on social media, while members of his team continued to publish investigations into Russia’s corrupt elite from exile.
